A humming outdoor unit with a fan that will not turn is the call we get most in July in Montgomery, AL, and the cause is usually a failed run capacitor. That inexpensive component starts the compressor and fan, fades for years without complaint, and then quits under peak load. It is far from the only suspect, though. Contactors pit and stop passing clean power, condenser fan bearings dry out, small refrigerant leaks drain away cooling capacity, and evaporator coils ice over when a clogged filter strangles airflow.

When to Call for AC Repair in Montgomery
Recognizing the warning signs early can save you time and money. Watch for these telltale signs:
- An AC that turns on and off every few minutes but never cools down the house
- The outdoor unit humming or clicking but the fan not spinning
- A hot electrical smell or a tripped breaker whenever the air conditioner kicks on
- Puddles near the air handler or water stains on the ceiling beneath it
- Vents blowing air that is barely cooler than the room
- Ice on the refrigerant lines or a frozen indoor coil
- A hiss or gurgle from the lines, a common sign of leaking refrigerant
- Cooling bills climbing while the house stays sticky and warm
